Towards evidence-based percutaneous coronary intervention: the René Laënnec lecture in clinical cardiology.

Abstract

Percutaneous coronary intervention (PCI) has matured from a pioneering adventure focused on feasibility to a major sub-specialty delivering real clinical results to patients. Despite delivering reductions in mortality and morbidity in the field of acute coronary syndrome and overcoming in-stent restenosis, several challenges still remain. Firstly, we need to adhere to practices supported by established trials: data relating to PCI in stable angina and late reopening of occluded infarct-related vessels suggest that this is not always the case. Secondly, we must develop new trials asking clinically relevant questions in 'real-world' populations that are focused on patient-based outcomes. Finally, given the current global financial crisis, it is now more important than ever that we demonstrate cost-effectiveness in our clinical practice. In these turbulent times, we discuss the challenges ahead for PCI in its journey towards evidence-based practice.
